Adaptation of postural symmetry to an altered visual representation of body position

摘要

The goal of the present study was to determine whether postural symmetry can be altered through sensorimotor adaptation. A gradual change in postural symmetry was induced in participants by biasing visual feedback of their body's center of pressure toward the left or the right. Results showed that this procedure induced a significant shift in participants' stance, which resulted in postural asymmetry and altered postural control that persisted beyond the period of altered visual feedback. We discuss the implications of such visuo-motor procedures for the rehabilitation of patients with postural asymmetry.
